BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to bedroom accessories. More specifically, the present invention pertains to an improved temperature control pad that is configured to be placed underneath a conventional mattress to heat, cool or scent the same.

Many parts of the world experience heat waves, and people have trouble sleeping when it is just too hot. Research has shown that there seems to be an ideal temperature for sleep and when this temperature is very high, it takes longer to fall asleep, and once sleep is achieved, it is broken up or fragmented and there is less dreaming. There are tricks to keep a bedroom cooler like using blinds to keep sunlight out or keeping windows closed if the temperature outside is much hotter than inside. People will also have their air conditioning on in their dwellings. However, it is often not enough nor cost effective to continuous run the air conditioning.

Additionally, there is a problem with multiple people sleeping in a house. People sleeping in the same circumstances may have a totally different night's sleep; one sleeper sweats through the night; the other one shivers through the night. Based on a plurality of factors such as perception and tolerance of cold, metabolism and body size, sleepers can be generally divided into two categories: warm sleepers and cold sleepers. Many people that usually sleep hot are often naturally warm sleepers or because they experience hot flashes or night sweats. Other people have the opposite problem of sleeping cold and complain about being cold despite sleeping in the same situation as a warm sleeper.

The present invention provides a temperature control pad that is designed to help a sleeper stay warm or cool at night while sleeping. The temperature c control pad includes a rectangular pad that is placed underneath a conventional mattress. The rectangular pad includes an interior volume having a plurality of tubes disposed within. The plurality of tubes have a plurality of apertures that are configured to disperse air therethrough and permeate through an upper surface of the rectangular pad. The rectangular pad is connected to a control unit through an air hose, wherein the control unit includes a control circuit and a blower assembly configured to direct air therethrough and to the rectangular pad. The control unit is electrically connected to a control panel that allows a user to control a fan speed, a temperature, and a release of fragrance.

2. Description of the Prior Art

For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used underneath a mattress to provide fragranced and cooled or heated air around the bed. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.

Referring now to FIG. 1, there is shown a transparent view of the temperature control pad 20 for heating, cooling and releasing fragrance underneath a mattress. The temperature control pad 20 comprises a rectangular pad 21 having an upper surface 90, a coextensive lower surface, an upper end 51, a lower end 52, and opposing sides 53 forming an interior volume. The temperature control pad 20 is configured to be placed under a mattress and is similarly sized to different sizes of conventional mattresses. The interior volume comprises a plurality of tubes 22 disposed within in rows. The plurality of tubes 22 comprise a plurality of apertures 23 along the length of each tube 22 that are configured to disperse air therethrough. The plurality of tubes 22 are joined together at a first connecting end 24 on the upper end 51, wherein the plurality of tubes 22 and the first connecting end 24 are in air communication.
